Application filed November 10, 1922. Serial No. 600,975.

This inventionvrelates to a cleaner for boilers particularly designed for removing mud or analogous sediments from within the boiler and discharging it through the blowV oi' line vor pipe of the boiler structure.

One object of this invent-ion is to prof vide a device kas specified which may be .Y mounted upon the main easily installed in a boiler structure and one which is adjustable to lit various sizes and types of boilers.

Other objects of the invention `will appear in the following detailed description taken in connection with the accompanying drawings wherein: j

Fig. 1 is a longitudinal section through the mud drum of a boiler, and through the improved cleaner or mud extractor.

Fig. 2 is a cross section taken on the line 2 2 of Fig. 1. n l

Fig. 3 is adetail section on the line 3-3 of Fig. 2.

Fig. 4 is an enlarged detail section.

f Referrin more particularly to the drawings, boiler is illustrated, which has the blow oit pipe or line 2 connected thereto. The im` proved cleaner is associated with theblowo line or pipe 2 for discharging mud and other sedimentv therethrough and` it comprises a nipple 3 extending into the connecting fitting 3 for threaded engagement therewith.v This connecting fitting 3 carried by a blow-oit pipe 2. The nipple 3 has `threaded engagement with a coupling 4: body or pipe 5 of the cleaner. The main body or pipe 5 of the cleaner extends longitudinally within the l drum 1 in close proximity to the bottom thereof and is provided with a plurality of longitudinally spaced openings 7 opening out towards the lowermost portion of the drum, as clearly 4shown in Fig.,1 of the drawings.

The pipe 5 is suspended in the drum by spaced supports 10 which are similar in con struction. Each a rod member 11 whichhas a saddle 12 attached to its upper end. This saddle 12 has its opposite ends up-turned as at 13 and these upturned ends are secured to the adjacent wall ofthe drum in any approved The rod membery 11 is connected through the medium of a turn buckle 14 to `one end of a rod structure 15 which comprises a rod 16 having a longitudinally ex- Afor engagement with the pipe 5.

a mu drum 1 of any approved type of of the supports. 10 includek tending recess 18 formed in an end portion thereofl for the .accommodation of a tongue 19 formed on the rod 17. The tongue 19 is pivotally connected to the ro'd 16 by a pivot pin 2O so as to permit the rod 16 to be moved pivotally relative to the rod 17 thus per1nitting the rod 16, turn buckles 14 and'rod member 11 to be readily folded upon the rod 17 when placing the device in the drum or when packing the device for shipping purposes. A sleeve 21 is slidably mounted upon the rods .16 and 17 and is limited in its downward movement by means of a pin Q2. The sleeve 2O is adaptedto extend over the pivot joint between the rods 16 and 17 to lock these rods against pivotal movementwhen the device is mounted in operative position 'within the drum. The rod 17 has a saddle 23 attached thereto in any approved manner This saddle is connected to the pipe 5 in any suitable By adjusting the turn buckles 14, the rods 11 and rod structures 15 can be drawn to-A ward each other to effecta tight connection between the connecting iitting 3 and the adjacent wall of the drum eectively sealing the line of .separat-ion therebetween.

In use, when a boiler is blown out the Vpressure of he steam will cause the mud and sediment in the bottom of the drum 1. to be drawn into `the pipe 5 and discharged therefrom through the nipple 3 and pipe 2.

`It is, of course, to ybe understood that the invention may be constructed in other manners and the parts associated in dilierent relations and, therefore, I do not desire to be vlimitedin `any manner except as set forth in the claim hereunto appended.

Having thus described my invention what I claim is:

In a boiler, the combination with the mud drum and a blowuof pipe thereof, cfa con Y duit suspended in thedrum contiguous the lowermost portion thereof and in Isubstantially a horizontal plane, a nipple connected to said conduit and extending vertically through the bottom of the drum, a connect-1 ico each of said other rod members including sectional; parts pivotzilly connected together, corresponding end portions of said other rod members being` connected to the conduit, means providing connection bet-Ween theopposite corresponding` end portions of said other rod members and the opposite corresponding end portions of said firstmentioned rod members, the last mentioned means permitting adjustment between said first mentioned rod members and said other rod members in a direction to bind the connecting tit-ting against said adj scent Wall portion of the drun'i.

In testimony whereof I affix my signature.

GEORGE A. SCOTT.
